Kousuke has a boring high-school life, but he sits next to his
crush--the really popular, cute Tsukahara Meguru, who has a cool, stoic
personality. One day, his parents announce that they're moving, but that
he'll still be able to attend the same school. The new apartment
building has a lovely river and friendly neighbors... and it is next
door to where Tsukahara lives! Outside of school, she seems to have a
completely different personality, friendly and a little quirky. She
makes him promise not to tell the others at school how she acts at home,
but why does she put on such an act for her classmates?
